3 Reel Slots

Three-reel slots, also referred to as classic slots, are slot games with three vertical components or reels. Traditional slot machines started off by featuring three of such components. The very first slot machine, Liberty Bell, incorporated four symbols; a heart, a spade, a diamond, and a cracked bell, across three reels.

As technology progresses, traditional elements become more conversational than practical. While this might be true in part for classic slots i.e., mechanical slots, three-reel slots are still enjoyed by a huge number of casino free slots players.

In my opinion, three-reel slots have their foundation cemented in the world of gambling. No slot mechanic fancy enough can replace the simplistic and traditional element of a three-reel slot. However, technology has increased variability in these slot machines and even brought to life 5 reel slots.

An Introduction to Classic Slot Machines

A slot machine is defined as a machine that generates a game based purely on chance. Most casino slots games operate using a random reel modifier. The probability of a player landing a winning combination is based on a collection of symbols aligning themselves in a particular way to trigger a win. Winning combinations usually feature similar symbols aligning in rows of three (if not more or less).

The term ‘slot machines’ was originally used to refer to both vending machines and gambling games. In the 20th century, the term became more specific and is now used to refer solely to the latter. However, gambling devices are also referred to as the following:

  • Fruit Machines
  • Puggies
  • Poker Machines
  • The One-Armed Bandit

Liberty Bell and Some of the World’s First Slot Machines

The first mechanical slot machine, the Liberty Bell, was introduced in 1895 by car mechanic Charles Fey. Nearly a century later in 1975, the Fortune Coin Company released the world’s first electronic slot machine.

From the time the first mechanical slot machine was introduced till the time the first electronic one made headlines, all slot machines operated using three vertical compartments or reels. In fact, Operator Bell was created as a knock-off version of Liberty Bell that incorporated the same number of reels, but with different symbols.

Original slot machines were cast iron slot games that featured three reels with ten symbols printed per reel. A lever was attached to the side of the machine. Players pulled the lever and tested their luck.

In the case of Liberty Bell, players needed to land three matching symbols aligning themselves in a row to trigger a win. Fey incorporated four symbols in his device:

  • Hearts
  • Spades
  • Diamonds, and
  • Broken Bells

The broken bell was the highest paying symbol; the payout was between fifty cents and a nickel.

Today’s Modern Slot Machines and How Times Have Changed The Online Casino Industry

Today, we have several versions of three-reel slot machines. These include electronic ones, video slots, and online slot machines. Thousands of three-reel slots have been developed based on various themes and incorporating different symbols.

The three-by-three setup for these slots remains the same even today. However, gaming developers and software engineers wanted to bring more ingenuity into the world of slot machines by introducing five-reel, seven-reel, and even ten-reel slots.

If you were to either visit a land-based casino or an online one, you’ll find hundreds if not thousands of slot games to play. These games differ in one way or another from the next. However, one thing’s for certain: no slot game can ever replace the humble three-reel slot.

How Have Three Reel Slots Managed to Stay Relevant?

Players are quick to assume that three-reel slots are all vintage, outdated, and boring slot games. Three-reel slots have always been the first of their kind across all categories and subcategories of slot games.

This is due to the fact that three-reel slots have the simplest design, mechanics, and are easier to comprehend.


Matching two or three symbols of a kind on a payline will be enough to trigger a win in three-reel slots. Your gains will be determined once a line crosses through one symbol on each reel; usually from left to right. Most slot machines feature fruit symbols, but modern slot games can feature almost anything. There’s also only one payline.

More recent three-reel slots have upwards of ten paylines. These paylines can be triggered either horizontally, vertically, or diagonally

Volatility or Variance:

It is, however, noteworthy that a majority of three-reel slots have high volatility or variance.

Volatility or variance in a slot machine is used to refer to the probability of a player landing a winning combination. To put this in context: a game with high variance, such as a three-reel slot, is less likely to trigger a win. However, when it does, it generates larger wins than other slots with low variance.

Highly volatile three-reel slots often include blank spaces in their reels. They’re found in the middle of each symbol within a reel. Blank spaces have no value but are included in highly volatile slots with higher payouts.

Three-Reel Slot Gameplay:

Three-reel slots are the simplest slots that can be played. In fact, these slots are particularly loved by casino novices who want to build up their skill and by experts to relive a sense of nostalgia.

Since you’ll be playing these slot games for actual money, it’d be a smart move to understand how they work and how much they pay out. First thing’s first, check the paytable and familiarize yourself with the statistics and symbols of the game.

Most three-reel slots have wild symbols, scatters, and several multipliers. From the paytable, ascertain how much each one of those symbols pays and what would trigger a multiplier.

You can place your bet per spin or per payline. For slots with more than one payline, you’ll want to bet on all paylines - you don’t want to miss out on a winning combination formed on a payline that you didn’t bet on.

3 Reel Slot Graphics: How They Have Evolved Over Time

The first slot games to have ever been released, whether they were mechanical, electronic, or completely video-based, were all modelled after three-reel slots. This is in part because three-reel slots are simplistic in their design and functioning. Three-reel slots, therefore, serve as a template for all new releases.

Graphics for three-reel slots have changed considerably over the years. Older games such as Double Diamond feature older graphics and themes such as retro visuals and sounds. Newer versions of three-reel slot games feature more modern mechanics, designs, and animations.

Older versions of three-reel slots include:

  • Double Diamond
  • Triple Diamond
  • Triple Joker
  • Chinese Kitchen
  • Hot Chilli

Newer versions of three-reel slots include:

  • Jackpot Jester 5000
  • Bermuda Triangle
  • Mystery 7
  • Crazy Joker
  • Sunset Delight
